1. Event background:
Due to the use of the win8 system, the Guo Tianxiang C51 development board purchased before has a problem when downloading the program through a download cable with usb ports on both ends: the download tool stc isp cannot be connected to the serial port on the development board, so the program cannot be downloaded to the c51 On the development board, the error is displayed as follows
2. Seek solutions
I have tried almost all methods on the network, including updating the driver, restoring the driver to an old version (may be useful, but I didn't use it) and so on without success. This led me to almost give up the board at the time. In the process of trying, I also thought about using u to serially connect the serial port on the board to the usb port of the computer to download the program, but it was unsuccessful.
3. Step through the iron shoes, there is nowhere to find it, and it takes no effort to get it
By chance,
I found a way to download the program
:
First open the stc isp software, set the settings, connect the u to the serial port, first connect the board and the computer, first turn off the power of the board, click the download on the stc isp, and then turn on the power of the board, at this time, you will Find that your program is downloaded to the board. (Note that every time you download a program, you must first turn off the power, then click the download program, and finally turn on the power, remember)
4. Further research is required
The specific reasons are not yet clear, and further research is needed.
5. Thank you all
Due to my limited level, if I have any mistakes, please correct me, I would be very grateful!
